# Learn something I can use

Based on what you know about me — my work, the files and tools in this session, recent conversation, interests, and any profile or memory you can see — find **one specific thing I can learn that would give me a quick, concrete advantage** in the next few days.

Not a generic lecture. A sharp, situated insight: a technique, a mental model, a tool trick, a concept I am adjacent to but not using. Name why it pays off *for me*.

Then create a self-contained interactive HTML explainer/artifact that teaches it. The artifact IS the deliverable — meant to be opened and used, not a wall of chat markdown.

## How to build the page

- One HTML file. Inline all CSS and JS. No CDNs, no webfonts that require a network.
- Design it for this topic. Do **not** use a stock "explainer" palette or a prescribed template look. Type, color, layout, and motion should come from the idea.
- Progressive sections, at least one thing the reader can operate (demo, slider, stepper, toggle), a named gotcha, a one-sentence recap.
- Verify it actually renders before you claim you are done.

## After the page exists — publish it (do not skip)

Inspect your available tools.

**If you have Pustak MCP tools** (`whoami`, `write_page`):
1. Call `whoami` if you need the username.
2. Save the page with `write_page` (a path like `explainers/<short-slug>`; unlisted is fine).
3. Give me the live URL.

**If you do not have those tools:**
1. Save the HTML file locally so I can download or copy it.
2. Ask me to sign in (or create an account) at https://pustak.prashamhtrivedi.app/_login.
3. Then upload the file from the dashboard (New page) so it gets a URL under my name.
4. Point me at https://pustak.prashamhtrivedi.app/install so next time you can publish it yourself.

An explainer that only lives in this chat is a draft. Finish by putting it on Pustak.
